The popose of this investigation is to a novel method for production of hydrogen by photocatalytic decomposition of liquid water.The semiconductor fine powders such as cadmium sulfide, copper (I) oxide, Gallium (III) oxide and others were thinly coated with polymer by means of capsulated polymerization method and other method. These modified semiconductor particles were suspended into water and irradiated using 500W xenon lamp.From experimental results, the encapsulated semiconductor particles with polymer such as polymethyl methacrylate, polybutyl acrylate and colloid titration polymer by polymerization method and other method had no photocorrosion, narrower band gap, no poison, making them sensitize to the visible ray and high energy efficiency, and were found out to be new excellent photocatalysts for production of hydrogen by water splitting.

这项研究的浮雕是通过液态水的光催化分解来生产氢的一种新方法。半导体细粉，例如硫化镉，铜（I）氧化物（I）氧化物（III）氧化物（III）和其他粉末，用封闭的聚合方法和其他方法用聚合物薄薄地覆盖。将这些修饰的半导体颗粒悬浮在水中，并使用500W氙气灯辐射。从实验结果中，与聚合物（例如聚合物）封装的半导体颗粒（例如聚合物甲基丙烯酸甲酯，多丁基丙烯酸酯，多丁基酯）和胶体滴定的聚合物无毒物，而不是毒物的能量，而不是光电连接，使得photocorlosizion the trapocorsible，使得射击量，使得射击量，使得射击量，使得射击量，使得光电剂，使得射击量，使得射击量，使得射击量，使得射击量，使得射击量，使得降低了光电剂，使得射击量，使得光电剂量，使得较高的滴定量。效率，被发现是通过水分割生产氢的新型优质光催化剂。
